my question is what would be a safe rpm/HP level with this crank and rods? I got a great deal on the shortblock and I am just hoping I can use it safely.
My car is geared for 1/8 mile with 4.86, all but 1 of the tracks I race at is 1/8. but if I sneak off to the 1/4 mile track I would need about 7400 out of this...
thank you for your help...
I wouldnt want to take it over 7000 but thats just me you can get away with it though. I had a gm crank in my 468 last year, it was a decent crank not sure what motor made but ran 8.0's@2000lbs
